WINDOW-SCREEN.

Specification ofLet'ters Patent.

Application filed Dctober 2'7, 1908.

Patented June 8, 1909.

Serial No. 459,683.

To all whom it may concern:

Be it known that I, WILLIAM HENRY MILLIs, of Canastota, in the county of Madison, in the State of New'York, onset? the United States of America, have invented certain new and useful Improvements in Window-Screens; and I hereby declare that the followi 0 is a full, clear, and exact description of t e same.

This invention relates to a window screen wound upon a spring actuated roller mounted in a WllldOW screen housin and it relates particularly to the housing or the window screen roller and to the guides attached to the window frame to embrace the side edges of the window screen, so that the window screen may be permanently or detachably connected to the window.

For an understandi of the invention reference is to be had to t e following description and to the accompanying drawings in which:- 1

Figure 1, is a pers ective view of a window showing the enera arrangement and con struction of t e parts of the window screen with the window screen housing partly broken away. Fig. 2, is a perspectiveview of the housing for one of the window screen rollers. Fig. 3, is'a erspective view of one of the guides for the side edges of the window screen. Fig. 4, is a view of the window screen bar and fastener. Fig. 5, is a view of a modification of the construction shown in Trike characters of reference refer to like parts throughout the specification and drawin s.

its the eneral construction of the window frame an window sashes has not been altered, it will not be necessary to describe these parts except when it is necessary to mention them in connection with the essen tial features of the invention.

At the bottom of the inner surface of the.

, ble parts d d", of'which the, part (1" slides into the adjacent end of the partd' so that the housing can be extended and contracted lengthwise. The housing at is preferably made of sheet metal formed to the required sha c, with one or both edges of the part (1 fol ed within the housing toform a gulde for one or more of the edges of the part 6" when the part (1 is being adjusted to the part 11. By makin the housing (1 of two parts (1 d it is ossib e to adjust the parts lengthwise of the ousing, so that the housin will accurately fit between the inner sur aces of the Window stops 6 without making any alterations to the window frame or Without having to perform any work upon the housing when fitting it between the window stops e. Secured to the window stops 2, at the sides of the window sash, are guides f which extend from the window sill g to the top of the lower window sash. The guides f are of a substantially U-shape to receive and embrace the edges of the window screen h. The window screen it is wound upon a s ring actuated roller t the journals 7' of whic are mounted in the ends (I of the housing d. Connected to the free end of the window screen h is a bar 7: adapted to be connected to the window sash. The connection between the bar and the window sash ma be either of a permanent or detachable c aracter. It is preferable however to make it detachable so that the window may be opened for cleaning and other purposes.

As shown in Fig. 4, the bar It is formed with a bayonet joint slot 1 to receive the head of the fastening in m and as shown in Fig. 5, it is formed wit a pocket 0 to receive the catch p. The guides f may be covered with felt or other fabric to enga e with the window sash and serve as a weat or strip, or they may be employed merely for the pur- .pose of embracin the edges of the window screen. The gui es f are provided with lugs q to engage the adjacent surface of the housmg (I to prevent the vertical movementof the housing during the revolution of the window screen roller. The upper sash is provided with a window screen, a window screen roller, housing, dguides, lugs and bar similar to those describe in connection with the lower sash. In the use of the invention the housing is accurately fitted between the window stops and the roller and screen are cut to the requisite size, and the journals of the roller are mounted in the ends of the housing. The

guides are fastened to the window stops, and the bar It is attached to the window sash with its ends contained in the grooves of the guides.

During the openin movement of the Wmdow, the window sas 70 carries the bar with it and 'unwinds the window screen from the roller. The ends of the bar move in the grooves of the guides and as the width of the window screen corresponds to the length of the bar the edges of the window screen move in the grooves in the guides during the movement of the window sash, so that the window guides will maintain the window screen in its correct position and prevent the formation of an openin between the edges of the window screen an window frame. When thewindow screen is attached to the window frame and sash, it is possible to quickly detach it from and reattach it to the window when it is necessary to do so.

Havin thus fully described my invention what I c aim as new and desire to secure by Letters Patent is The hereinbefore described device comprising two vertical guide members, secured to the opposite sides of the window frame, each having in its inner side a guideway for the window screen, a horizontal lug extending forwardly from each guide member and located sli htly above the lower end thereof, a housing %or the window screen unattached to any part of the window, consisting of two parts telesco ically united lengthwise of the ousing an substantially rectangular in cross section to provide a bearing on the bottom of the window frame and a second bearing against the horizontal lugs, a window screen roller mounted to revolve in the housing, a window screen wound thereon, and a bar attached to the window screen to stretch it laterally and by which it can be attached to the windowv sash.
